Validation of Wiener Fahrprobe – A method description.

On the decision of the Swedish government, the Swedish National Road Administration (SNRA) has started a large-scale trial with Intelligent Speed Adaptation (ISA) in urban areas. One of the four test sites is the city of Lund. At the Department of Technology and Society, Lund University, research about ISA has been carried out since 1986 and the first field study was carried out in 1993. The ongoi

Structural Models of Network Contacts Between Actors Governed by Activity and Attraction

This thesis consists of five papers on the subject of statistical modeling of stochastic networks. The NG-model proposed in Paper I combines a block structure with parameters that capture the identities of vertices and thus the new approach stresses the concept of ego-nets, which describes the structure around identified vertices. The models proposed in Papers II-V are closely related to the NG-mo

Sum Rules for Parallel Plate Waveguides: Experimental Results and Theory

An experimental approach to verify the forward scattering sum rule for periodic structures is presented. This approach allows an upper bound on the total cross section integrated over a bandwidth from a simple static problem to be found. Based on energy conservation, the optical theorem is used to construct a relation between the total cross section and the forward scattering of periodic structure

Discrete-Time Cellular Neural Networks Implemented on Field-Programmable Gate-Arrays to Build a Virtual Sensor System

Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. At first glance a pipelined approach, based on circuit switching, seems promising. The digital implementation supports the handling of grey-level images at 180 to 240 Mpixels per second by exploiting the Xilinx Virtex-II macr
